I want to know the places of the service centers in the Gulf region.

Samsung Gulf supports ( UAE, Bahrain, Kuwait, Oman, Qatar) and there are many service centers supporting Samsung Products all over the Gulf region. All you need is just to visit the link below and choose the city you are in, select the product category, and search within the range of 10-50 Km to get all the service centers located in the chosen place.
